AND AR ATTACHMENT FOR INLET-MANIFOLIDS,`

Tall/whom it may concern.'

Be it known that I, \ViLLi.\.\i L. Hmm, a citizen of-'the United States, residing at Eaton Rapids, in the county of Eaton and State of Michigan, have invented certain new anduseful Improveinentsin later and Air Attachments forInlet-Manifolds, of

, which/the following is a specification.

'The' invention has for an object to provide desirable lmeans for introducing auxiliary constituents into the charges for internal combustion engines, and seeks particularly` to present a simple attachment suitable for use upon anyordinary engine already constructed without modifying the structural details or mode of operation.

An important aim is to give a desirable.

mechanism yfor admitting water tothe intake manifold of internal combustion engines.

A further important objectis to makeavailablev adesirable and efficient means for controlling and modulating auxiliary air and water feeding devices;

Additional objects and advantages will be apparent from the construction, arrangenient, and combination of parts hereinafter set forth, 'and shown in the .drawings,\in which,-- l

Figure 1 illustrates my invention installed-upon a motor vehicle of ordinary type, Fig. 2 is a dctail edge view of the devices 22.*and 23, each of similar form and vice with partof the; cover removed, Fig. 3 is a sectional `view in the, maJor medial plane of the device.

There is illustrated an intake manifoldv 10 upon which there is secured a body `casting11 of a suitable material in'which there are formed two vertical parallel bores 12 and 13, smoothly finished and-terminating in conical seats 14, opening through the centers o'flwhich there are passages' 15 and 16 respectively. The passage 15 opens through the lower end of the casting and' suitable.

connections 17 ai'e provided leading to the manifold 10 therefrom.' The passage 16 opens through the side of the block, and water supply connections 18 are provided therefor. Immediately above the seats 14 a horizontal passage 19 is formed in the cast- `ing intersecting the `bores 12 and 13 and .having an air inlet valve 20 at its outer end. A valve 21 is also provided upon the water supply 18, as shown. Snugly itted in the bores 12 and 13 ,there are needle valve de- Specification of LettersPatent.

comprising a cylindrical body portion having a multiplicity of circumferential parallel oil grooves 24, the lower end being' reduced -for a distance as at 25 and 'terminating in a conical portion 26 with a more` gradually tapered portion`27 adapted to project into the passagel' or '1G as the case may be. Pivot ears :2S are formed at the upper ends of the valve members 22 and 23,

,upon lwhich there are' pivoted respective 'links and 30. Carried upon thefmember 11 there is a cover or casing 31. in which there are carried sleeves 232, threaded iii 'suitable openings in the top of the casing, the

sleeves being alined.respectively with the bores 12 and 13 and being secured `adjustably by lock nuts 33. Slidably engaged in these sleeves there are headed pins 31, vwith their heads presented downwardly and borne against the upper ends of the linksv 29 and A30 by 'springs Pivoted upon suitable lugs 36 on the body l11 at one side of the casing 31 there are two bell crank levers '37 and 38, connected respectively to the upper'ends of the links Quand 30 at the ex` tremity of one arm, while the otherarm of each extends upwardly through ak suitable slot 39 in tlie top of the casing.

The body 11, for convenience in manufac-v ture and facility in installation,l as well as to' adapt the device most readily to the space available `in the average motor vehicle hood, is forniedof a rectangular block ofbrass or other soft metal-of a non-corrosive nature having a thickness'but little greater than the diameter. of the bores 12 and 13 in one direction. |The body is arranged on the manifold with one of'its broadersides tov'- ward the engine,l and the casingl conforms Ato theshape of the upper edge'of the'bloc'k `to the link 30. On the foot board 39 there is pivoted apedal 40 to which links l-lare slidably connected, pivotally connected to the respective levers and 38. The rearl threadedand ,havraiengaged thereon adjusting nuts 441, ,against which the'petlal strikesunder foot pressure to draw iipon'the links, these nutsbeingse-*Q curedr; y loch nuts 42. The adjusting nuts are ar anged so that a' certain lamount of movement of the valve 22 will occur under pressure on the pedal before the valve 23 is operated',-although this arrangement is notk arbitrary and may beyaried as desired. vThe advantages of an auxiliary air supply .upon theintake manifold and of introducf.

ing moisture intov the fuelmixtureare well understood and Will not requirev detailed presentation. It is-important to note that by the device herein presented it is possible to supply auxiliary air without' admitting- Water, if desired, andthe device may also be adjusted to be operable toadmit air7 or air and Water, at will, governed by the degree of movement of the foot pedal.

A. liberall quantity of, oilA may be maintained in thefcasing 31, so that lthe yalves 22 and 23 will be welllubi'icated and an oil seal yformed therearound. j The air inlet duct- 19 may be coimected. in` any desired Way with ""a'h'otfair pipe, notl shown, and the water v supplyj'for the connections 18 may be either Bviates the liability f if a small receptacleattached to the side of the motor, or the usuai radiator with' which,

connections may be madellas at 43, prefer'- ably near the upper part inonder tliat'warm water may be assured` although the device will operate Well with coldglwuter.

In use, the engine is started and operatedA in the customary manner, and the auxiliary air` vand water Supply controlled by the operators foot, in .accordance with the need. If ydesired any suitable familiar detent may be provided to hold the pedal releasaibly "arious points inv its movement.

It should be noted thatvbythe arrangement of the valves and passages a double .valve seal is formed between the Water sup-V .ply Aand the manifold, guardingl Well against casual inlet of water when not desired.

arrangement also insures the regularity 'of The thepwater feed, the feeding` of Water to the airY inlet passage 19, causing it to be car- 't e'passage 15, to the manifold, vvhere it is projected in a fine spray. FThis arran ement l regular fee ing'of the water, and insures an, evenv supply and mixture. f v f What is claimed: .c
